Lawn is in southwest Oregon, not sure of the seed mix, probably fescue, Kentucky bluegrass etc. Poa annua is gradually spreading in 3 year old lawn. I am looking for a post emergence product.
Dimension 2EW Herbicide can be used to help prevent poa annua from emerging but will not effect any actively growing poa annua. Most products that are labeled for poa annua cannot be used on KBG as they are both cool season bluegrass types. We recommend that you spot treat the poa annua using a non-selective herbicide such as GlyPhoSel Pro and then reseed the areas.
